纯碱2601合约分析简报 分析日期: 2025年8月14日 品种/合约: 纯碱(SA)/ 2601合约 核心观点: 纯碱2601合约自6月低点反弹后进入回撤再企稳阶段。当前市场表现为“量放、价稳、仓增”,日线图显示偏多态势。然而,MACD动能尚未翻正,表明短期动能仍显不足。因此,本报告建议以“回踩做多”为主要策略,波段操作(4-7个交易日)为本轮推荐。 主要发现与证据: 市场节奏与当前状态: 纯碱2601合约在经历6月低点反弹后,进入了回撤并重新企稳的阶段。 当前的显著特征是“量放、价稳、仓增”。报告指出,“近三日成交放大、价格重回均线之上,持仓同步放大”,表明市场获得支撑。 结论(一句话): “纯碱 2601 自 6 月低点反弹后进入回撤—再企稳阶段;当前量放、价稳、仓增,日线仍偏多,但 MACD 动能回落尚未重新翻多,短与波段节奏以“回踩做多”为优先,趋势仓谨慎递增。” 核心证据(2025-08-14 收盘数据): 价格 (价): 收盘价1400,站上布林带中轨 (BB_mid≈1380.8)。价格高于EMA12 (1371.5) 和EMA26 (1345.4),呈现多头排列。 成交量 (量): 5/30日成交量振荡器为+99.6%,显示“显著放量”,支持价格企稳。 持仓量 (仓): 持仓量连续5日上升,当日增长5.28%,指向“资金回流而非纯脉冲”。 动能指标: RSI(6/12/24) 分别为59.8/57.8/56.4,均在50以上,动能偏多但“非强势极端”。MACD柱状图(-7.18)仍为负值,是当前偏多趋势中需要警惕的因素。KDJ指标中K>D,J值高位但未极端钝化。 开仓确定性级别(量化打分): 信号一致性(图像/指标/基本面):≈60/100 回测胜率(简易规则):≈50/100 夏普标准化:≈66/100 综合得分: 58(中确定性)。建议“可择机小仓布局、以回踩承接为主”。 交易周期建议: 波段交易(4–7个交易日) 为主推荐。理由是“量仓配合但 MACD 柱未翻正,短期以‘回踩承接、分批加减’节奏更优。” 图像层面分析: 价格自6月24日低点后整体抬高,重新站上中期均线区域。 阳线日普遍放量,同时持仓线抬升,印证资金回流。 KDJ/RSI指标显示动能偏多但非极端强势。 图像因果结论: “量→价→仓呈偏多结构;需警惕 MACD 柱未转正导致的节奏反复。” 基本面与数据来源: 报告强调数据来源的“优先用官网、交叉验证”原则。 郑商所官网的“纯碱期货/期权”合约与规格、仓单日报、业务/交割细则、新闻月度统计口径是主要数据来源。 基本面结论: “规则口径清晰、数据路径完备;短期交易以技术与量仓为主,仓单/库存变化作为趋势延续或反转的‘二次验证’。” 多维度交叉验证: 图像因果链: 偏多 技术指标: 偏多但动能不足(MACD柱未翻正) 基本面口径: 规则与数据路径明确,仓单变动待跟踪确认。 策略构建与风控设计: 统一约束: 严禁进入交割月持仓(2026年1月为交割月,2025年12月最后一个交易日为可交易截止日);以交易日为唯一时间单位。 波段策略(4–7个交易日): 本轮主推荐。 方向: 回踩做多为主。 触发: 回踩1381–1389区(斐波回撤38.2%/枢轴点PP)出现日内放量新高结构则介入。 仓位: ≤50%(分两次建仓:首35%+确认加至50%)。 止损: 1368(PP−0.5×ATR)。 止盈: 第一目标1415(R1),第二目标1431(R2),到价分批止盈。 短线策略(1–3个交易日): 方向: 回踩做多。 触发: 方案A(突破跟随):上破1415(R1)且5/15分钟量能放大则多;方案B(回踩承接):1385–1390区企稳出现分时放量阳线则多。 仓位: ≤30%。 止损: 1374(S1)或入场价−1.5×ATR≈−90.8,取更紧者。 止盈: 1430(R2);若突破并放量,则跟踪止盈。 趋势策略(≥10个交易日): 方向: 逢回补仓,突破加码。 触发: 日线MACD柱转正且价上破1431并站稳。 仓位: ≤70%(递进式,仅在动能转正后生效)。 止损: 日线EMA12失守或收盘跌破BB中轨。 风险提示: 本报告为研究交流,不构成任何形式的投资建议。 期货交易具有高风险,务必严格风控并遵守交易所规则与监管要求。 未来展望: 后续将把“仓单变动率”、“产销开工率”、“基差/价差”纳入深度因子回归,量化其对盘面的边际影响。 将“仓单日报”数据接入,做价-仓单-持仓三维图跟踪,以实现更全面的监控。 ---This image is a financial chart displaying various indicators for "Soda Ash 2601".
